Something to note about Skytrak is that currently it only gives ball data (spin, distance etc). It will not provide measurements on your actual swing. The unit itself must be next to the golf ball, and some people have had issues with damage from errant swings. However, Cory believes Skytrak is going to fit the needs of most golfers at this price level. SkyTrak has several software integrations that will allow you to play golf courses and has a tremendous native software package for practice.
